Yes, if they are thinking about deploying vertically to a LEO satellite then perhaps LoS is not an issue unless you are indoors. But if you want to require the user install an antenna or receiver outdoors then it can work, but again, the atmospheric loss can be an issue, for example if it is cloudy outdoors then light will have difficulty getting through that. Some wavelengths may be better than others but anyone who has had satellite TV knows what happens when it rains. But I do think what they are doing is interesting and has a long term promise for a lot of use cases.
